LOG-TURNER.

EPECIFICATI-ON forming part of Letters Fatent No. 293,316, datedFebruary 12,1884.

Application filed December 13, 1893.

zen of the United States, residing at Zoar Station, in the county ofTuscarawas and State of Ohio, have invented a new and useful Log-Turner, of which the following is a specification, reference being hadto the accompanying drawings.

This invention relates to log turners for saw-mills; and it has for itsobject to provide a simple and efficient device which will readily turnlogs by steam-power, and which may be attached to any saw-mill.

It also has for its object to provide a device which will operate, witha small amount of power, to turn the logs as fast as required; and afurther object of my invention provides means whereby the operatingmechanism may be thrown into engagement at will and out again attheproper moment.

With these and other objects in view the said invention consists incertain details of construction and combination of parts, as hereinafterset forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of myimproved log-turner in position on the saw-mill. Fig. 2 is a ver-. ticallongitudinal sectional view of the log turner. Fig. 3 is'a detailtransverse sectional View taken through the operating-shaft. Fig.

4 is a similar view, but taken at right angles thereto, through theoperating-lever which throws or brings the devices into engagement.

Like letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates the base-frame of thelog-turner, from which extend two uprights, B B, having braces orsupports 0 G,'and transverse connecting-strips I). A lifting-lever, E,is fulcrumed between the uprights at their top, and carries at one end apivoted lifting-hook, F, suspended from a cord, G, and has a cord orline, H, evtending up from its other end, said line working over apulley, I, connected to the upper end of a /\-shaped frame, J,and'having a weight, K, secured to its end, and serving by its gravityto aid in lowering the hook end of the lifting-lever. The A-shaped frameJ is journaled at its lower end in a transverse beam, L, secured to thebase A, and is adapted to (No model.)

connecting the said frame to the uprights B, said rods being jointednear their middle, to allow the slight forward movement of the frame.

N designates the log-carriage, of the usual construction, and upon whichthe log 0 is placed, said carriage having secured to its other endaframe, P, having a rotary operating-shaft, Q, journaled therein. Apulley, R,

loose belt or rope, S, with another pulley, T, sliding freely over arod, U, secured to the sides of the frame P. A drum, V, is formedintegral with the pulley T, and slides loosely over the rod U in asimilar manner, an annular shoulder, WV, limiting the movement of thedrum. 7

X designates a cross-bar, secured to the frame P at one end, and havinga hanger, Y, fitted to its other end, said hanger carrying apulley, a,at its lower end, andpivoted in an arm, Z, attached to one side of ahandle or lever, A journaled in the frame P. A hooked rod, 13,

opening, b, in the hanger, to hold and brace the latter in true verticalline. A cord or rope, O is connected to the drum V, and passes outward,through the framel and below the log- A. After passing through saidpulley D the rope extends 'upward through a pulley, E journaled in ablock, F depending from the under side of lifting-lever E, and thendownward through a pulley, G secured to base A, the end of said ropebeing secured to the lower extremity of the pulley-block F.

The operation of my invention will be read ily understood from theforegoing description, taken in connection with the annexed draw ings.When the hook end of the lifting-lever is .drawn down to enable the hookthereon to be engaged in the log, the hand-lever A has simply to beoperated to cause the pulley ato draw the loose belt S tight, when theoperation of the rotary shaft Q will, by means of pulleys R T, cause therope O to wind upon the drum V. The said rope as it winds upon therevolving drum will of course draw down the power end of thelifting-lever and raise the hook end, which thereby turns the log in themanner well known in the art. This movemove freely forward and backward,rods M- carriage, to a pulley, D, journaled in the base 7 is mounted onthis shaft, and connects by a is attached to the arm Z, and engages'withan ment of the lifting-lever has caused the rope J forward, so that whenthe limit of the rope O has been reached the hook end of thelifting-lever may be drawn down, the weighted cord H acting to assist inlowering the hook to its normal position.

It will be seen that the action of turning the log is positive and thedevice. for throwing the operating mechanism into operation is simpleand effective, the tension of the belt S being increased, so that theoperation of the rotary shaft will turn the drum and pulley to wind therope O in the manner stated. The rope or band S in its normal state istoo loose to transmit'motion from the rotary shaft to the pulley anddrum, and consequently it requires some such tension device as I havedevised to form a connection for the parts mentioned. It will beapparent that I do not limit myself to the particular device shown, asother means may be .employed to effect a like purpose.

The rotary operating-shaft is connected to the saw-mill and receivesmotion therefrom, so that the turning of the logs is effected wholly bysteam-power; and by reason of the connection'with the power end oflifting-lever a greater power is obtained than would be otherwise.

Having described my invention, I claim 1. In a log-turner, thelifting-lever carrying a hook at one end, incombination with the rotaryoperating-shaft, a pulley and drum formed integral with each other andmounted loosely upon a bar, a loosely-fitting belt connecting the pulleyand shaft, devices for increasing the tension of the belt, anduneans forconnecting the drum with the power end of the lifting-lever, as setforth.

2. Inalog-turner,thelifting-lever fulcrumed in suitable uprights andprovided at one end with devices for raising the log, in combinationwith means for operating said lever, a pivoted frame havinga jointedconnection with the uprights, and a weighted line connecting the powerend of the lever with the said frame, as set forth.

3. In alog-turner,thelifting-leverfulcrumed in uprights B, and providedat one end with devices for grasping the log, in combination with meansfor operating said lever, a pivoted frame working in the rear of thelever and provided with jointed rods secured to uprights B, which permitthe free forward movement of the frame, and .a weighted line secured tothe power end of the lever and passing through a pulley secured to theframe, as set forth.

4. In alog-turner,thelifting-leverfulcrumed in suitable uprights andprovided at one end with means for grasping the log, in combina tionwith a rope connectingwith the power end of the lever, a drum upon whichsaid rope is wound, a rotary operating-shaft, a l0osely-fitting beltconnecting the shaft and drum, and devices for increasing the tension ofthe belt at will, as and for the purpose set forth.

5. In alog-turner,thelifting-leverfulcrumed in suitable uprights andprovided at one end with devices for grasping the log, in combinationwith a rope connecting with the power end of the lever, a drum uponwhich the rope is wound, a rotary operating-shaft, a loose beltconnecting the shaft and drum, and a hand-lever provided with an armcarrying a pulley arranged to increase the tension of the belt at will,as set forth.

6. I11 a log-turner, the combination, with the rotary operating-shaft,of a bar arranged parallel with the same, a pulley and drum formedintegral and mounted upon the bar, a loose belt connecting the shaftwith the pulley, and a hand-lever provided with an arm carrying a pulleyarranged to increase the tension at will, as set forth. g

7. In a log-turner, the combination, with the rotary-operating shaft, ofa bar arranged parallel with the same, a pulley and drum formed integraland mounted upon the bar, a loose belt connecting the rotary shaft andpulley, a handlever, AF, provided with an arm,

Z, a hanger, Y, secured to the arm and carrying a pulley, a, across-bar, X, supporting the hanger, anda brace-rod connecting thehanger and arm, as set forth.

8. In a log-turner, the uprights B, provided with suitable brace-bars,and a lifting-lever fulcrumed between the uprights, a hook, F, attachedto one end of the lever, a weighted line secured to the other end, arope, O pulleys G D E", a drum upon which the rope is wound, and meansfor operating the drum, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of witnesses.
